■ A single object (to extrude multiple lines, convert them to a single object
with the
JOIN on page 533 command)
■ A single region (to extrude multiple regions, convert them to a single object
with the
REGION command)
To automatically delete the profile, use the DELOBJ system variable. If
associativity on page 1507 is on, the DELOBJ system variable is ignored and the
originating geometry is not deleted.

NOTE Select face and edge subobjects by pressing Ctrl while you select them.
You cannot revolve objects contained within a block or objects that will
self-intersect. REVOLVE ignores the width of a polyline and revolves from the
center of the path of the polyline.
The right-hand rule determines the positive direction of rotation. For more
information, see Control the User Coordinate System in 3D.
List of Prompts
The following prompts are displayed.
Objects to Revolve Specifies the objects to be revolved about an axis.
Mode Controls whether the revolve action creates a solid or a surface. Surfaces
are extended as either NURBS surfaces or procedural surfaces, depending on
the SURFACEMODELINGMODE on page 1509 system variable.
Axis Start Point Specifies the first point of the axis of revolution. The positive
axis direction is from the first to the second point.
Axis Endpoint Sets the endpoint for the axis of revolution.
Start Angle Specifies an offset for the revolution from the plane of the object
being revolved.
